DMSP OLS Decontamination Activity for F17
*Date/Time(UTC) Message Issued:*
15 June 2007/1715 UTC
*Satellite(s) Involved:*
DMSP F-17
*Instrument(s) Involved:*
DMSP OLS
*Product(s) Involved/Affected:*
Infrared Channel
*Date/Time(UTC) of Initial Implementation:*
18 June 2007, 04:26 UTC
*
Details/Specifics of Change:*
On 18/19 June 07; the NOAA Satellite Operations Control Center (SOCC)
and DMSP Engineers will perform OLS decontamination activities on
F17/Ops 51. Starting with the first orbit past midnight local eastern
daylight time on 18 June (the R+1), the thermal (Infrared) channel data
will not be available for up to 48-hours (until early on 20 June) and
could be degraded an additional 24-hours, until engineers have completed
final recalibration actions. Users of direct readout data (RTD) and
stored data from DMSP F17 should be aware of the loss of IR imagery.
To ensure uninterrupted collection of thermal OLS stored smooth imagery
in the early morning orbit, AFWA has requested IPO/SOCC mission planners
temporarily give F13 priority over F17 for playback site contacts for
the period 18-24 June. All other DMSP spacecraft will continue to
provide routine data collection support.
Visible channel data from F17 will continue however, scheduling of those
collections will be at a lower priority than F13 and F16 for the week.
There is no backup date for this activity.
